except that blood diamonds are NOT critical for world trade as a form of money. Bitcoin, otoh, has the distinct possibility to enable frictionless payments across all borders with a strictly known and fixed supply. yes, a gvt can perform irrational tainting acts but they risk isolating themselves and cutting themselves off from what has the potential to fundamentally change commerce. which nation wants to risk that?
Oh, I'm not disputing the triviality of diamonds, nor the ability of Bitcoin's anti-fragility to obsolete, ultimately prevail over, and finally replace TPTB.
My point is it will not be a painless nor victimless process, and we should watch our eggs to ensure they are not the ones broken for the sake of making the cryptopian omelet.
